FUN TRICK: If a BB starts with A-M = Selective. If a BB starts with N-Z = Non-Selective (B1+B2). The only exceptions to this rule are Carvedilol and Labetalol (B1+B2+A1 non-selective), and Nebivolol and Betaxalol (NO release vasodilation for Nebiv, and CCB-like response for Betax). You now know effectively every BB receptor!
That's an awesome trick! Thanks for sharing it with everyone!
Plz tell me wt is AM NZ
@@medicallecturersforgraduat1417 its drug whose initials from start A-M,,i.e drugs such as atenolol,bisoprolol etc and those whose initials lie between N-Z eeeh
It only works with the generic names though (eg Bisoprolol (generic name) versus Zebeta as its brand name. So don’t get confused. Great tip!!

Thank you for this video! I have Atrial Fibrillation and my electro cardiologist just put me on Metoprolol Succinate and Flecainide. The question I have is, do you have a video on Flecainide? I’m 58 years old and I haven’t had a need to take any medications until I developed A-fib recently. I’m just trying to educate myself about these drugs that I’m now having to take for the condition I’m experiencing. Thank you, and please keep the information coming on your channel.
How your dr realised you have AF pls
Excellent information I wish these high-paid doctors would take the time to explain this to you they just are like here's a bunch of pills good luck
Thank you for the support Mark! Appreciate the kind words😁
good stuff
good thsnk you dr
Good day. My doctor advised me to take propranolol 10mg once a day for about 1month for my chestpain. I’m now on the last 2pieces of medicine.. I’m just worried about the withdrawal syndrome after this.. Is it okay to stop it without tapering? It’s just a low dose anyway
OMG i was given propranolol just for my anxiety and it helps.
Why anxiety part is not covered in this video? Should i continue or switch to benzos? Which one is safe for anxiety?

Glad you enjoyed it! More videos coming out soon!
Great channel. Can you do a video on Alpha Blockers
Thank you for you support! @Miter Saw More videos coming soon, Alpha blockers are on the list to do! 😁
Thank you .good video. Can you tell me why patient is having bisoprolol and diltiazem together ?
Hi, is it true that discontinuing Propranolol can result in abrupt heart attacks even at low doses like 40 mg ?
Hi!😁
The risk will always be there when abruptly stopping any beta blocker. The risk is decreased if it's a lower dose, and a less duration of use (using it for 1 week versus 3 months). It never hurts to slowly taper beta blockers off!
Thankyou so much, this is so helpful , you git a new subscriber :)
Thanks for the sub!! :)

great
sir i am having a hard time finding the mechanism how B1 causes contraction in the heart ? any recommendations any one plz .
Good presentation.
Sir you have mentioned, in heart failure only 3 medicines ie, carvedilol bisoprolol metoprolol. So why nebivolol cannot be used bcz it could better replace carvedilol as the later even block beta2 receptor also. While the nebivolol do same as carvedilol without blocking b2 and since no lung issues
Supprbbb!!! N loved it
Thoughts on taking selective B1 Beta blocker while on Clenbutrol?
On it for thyroiditis overactive will it also help lower my anxiety and heart rate/ shaking
I got 4 points on your quiz. 😊
Woohoo!! Great job! @Aki Ra
I was put on propranolol because of heart palpitations caused by PVCs. It’s amazing how fast it works. I wonder what causes the PVCs. I always felt like I was having a panic attack, all day, every day for no reason. Not anymore 😁I usually hate rx because I always have the horrible side affects, but the only one I have with this is being cold because it slows the hr.
Bisoprololl has vasodilation effect aswel!!
I have a question, In what cases would non-selective beta-blockers be prescribed vs selective beta-blockers, given that many of the cases are heart-related issues? Thank you for your videos btw, super helpful and to the point, keep up the great work!! :)
Great question! You have to understand that the non-selective are older drugs. This means some insurance companies want to pay for them first, because they are cheaper. So unfortunately money is a big factor in therapy.
Also, some of the nonselective have benefits, for example: propranolol can be used for hyperthyroidism and social anxiety.
Hope that clears some things up!
@@DrugChug definitely cleared it up! Thank you so much for your help! :)
Non selective timolol somatol and propanolol
Can you answer what blood vessels alpha blockers cause vasodilation
So when adrenaline binds to alpha 1 receptor it causes vasoconstriction, did I understand right?

Best combination for 5mg amplodipine+ 40 mg proponol? please tellme sir.
Sir I take Inderal for anxiety disorder, my doctor has advised me to stop this medicine gradually like 10mg twice a day for a week and then 10mg once a day for a week before stopping it.
My question is that if I only take 10mg Inderal once a day whenever I needed can I stop it suddenly, and pls suggest which beta blocker will be suitable for my anxiety?
Hey Ashu, yes you should slow down taking the inderal just like you said.
If you decide to take it at times of need, it would be okay to take it once in a while without needing to lower the dose.
However, if you are using it only for anxiety, you must take it 1 hour before an event where you may get anxiety. If you need a medication for anxiety, maybe talk to your doctor for an anxiety medicine. Because Inderal is usually only for blood pressure.
Hope this helps!
@@DrugChug Sir, I'm grateful to you for your above advice and correct information. I understand that propranolol is basically used to lower the Blood pressure but its action of blocking beta receptors in the heart reduces the symptoms of anxiety. Which is great in dealing some social phobias like public speaking or an interview.
I visited a psychiatrist (DM) and he suggested me to take SSRI (Selective Serotonin Reuptake Inhibitor) this helps in maintaining the proper level of serotonin in the brain and it cures my anxiety in the correct way.
That sounds like a proper plan, I would work with your psychiatrist to develop a plan with an SSRI
@@DrugChug I have subscribed your channel to gain the correct and best information on drugs available throughout TH-cam. Thx
So how would u safely dismiss taking any beta blocker without the risks???
Sir how come beta blocker block alpha 1 receptor ?
Why are those three beta-blockers used in treating heart failure rather than different beta-blockers? Also great video, very informative and simple.
Great Question! @Calum
For a general answer: These 3 beta blockers proved to be superior in clinical trials for heart failure, and because of these trials, they are recommended.
The only other thing is that Carvedilol has antioxidant effects, which help reverse structural damage to the heart, which would surely help our heart failure patients!
Hope this helps!
@@DrugChug Thank you, it makes more sense. How do the antioxidants reverse the damage? And can most structural damage be reversed using the mechanism?
I use propranolol for anxiety and I had wpw I no longer have wpw
I have Heart failure and are prescribed Nebivolol.
How you doing?

I.ve been put on beta blockers as I have ischemic heart disease and small blood vessels disease my BP is high one minute then six hours later it's low
How does B1 blockers cause hypoglycemia?!
Do you have any pdf for the notes
Can carvedilol 12.5mg give to elderly patients? Does carvedilol slow down the heart function n the dilation of blood vessel to cause lesser blood to kidney n causing trouble to the kidney as kidney receiving less oxygen? How long can this medicine given to elderly patient? As the lung receptors are blocked n causing less function to exchange oxygen, could this result the blood cell in the body and organ deteriorate because of less oxygen and nutrients reqiired? Also, since carvedilol put a brake on the heart function, could this eventually worsening the heart n causimg death to elderly? This video is great, excellent explanation. One more question, since carvedilol is an old medicine, does it still widely used?
